<p>In a fuel distributor - in which the fuel to be delivered to a cylinder of an internal combustion engine is dosed by a metering valve - in order to maintain at a constant value the difference between the fuel pressure upstream of and downstream of the metering valve, there is provided a plurality of control valves (one for each cylinder) having a flat seat whose flow passage section is directly variable by a movable membrane. One side of said membrane is exposed to the downstream fuel pressure urging said membrane into a control valve opening direction, the other side of said membrane is exposed to the upstream fuel pressure urging said membrane into a control valve closing direction.</p> |
